Multiple Get Requests for Documents of Different Unrelated Types

[InsperDylan390]

Is your feature request related to a problem? Please describe.
I would like the ability to optimize my requests to Elastic using the Multiple Get functionality, but the current syntax returns all documents in a single list of TDocument responses.

Describe the solution you'd like
I would like the Multiple Get syntax to allow each individual get operation in the aggregate request to identify a specific TDocument type to retrieve and deserialize the found document into.

Describe alternatives you've considered
It might be possible to make a request for some generic shared type, but it would require a very robust deserialization strategy?

Additional context
I believe there are open issues for an equivalent issue in the multiple search functionality? Not as pressing, but it would be interesting to have the ability to Index documents of different documents of different types in the same request as well?

Hi @InsperDylan390 ,

that is nothing that can be implemented in the client library since this is very specific to the document types.

It might be possible to make a request for some generic shared type, but it would require a very robust deserialization strategy?

Yes, this is exactly the way to go.

The documents you want to retrieve should have a common base class and the required System.Text.Json polymorphism attributes.

Please let me know, if you have further questions.
